As height and sexual development are the two main things affected, Turner syndrome may not be diagnosed until a girl fails to show sexual development associated with puberty, usually between the ages of 8 and 14 years.

Other characteristics of Turner syndrome can vary significantly between individuals.

Treating Turner syndrome

There's no cure for Turner syndrome but many of the associated symptoms can be treated.

Girls and women with Turner syndrome will need to have their heart, kidneys and reproductive system checked regularly throughout their lives. However, it's usually possible to lead a relatively normal and healthy life.

Life expectancy is slightly reduced, but it can be improved with regular health checks to identify and treat potential problems at an early stage.
